I am writing a science fiction novel that is more soft that hard sci fi but I would like to know at least an estimat of the distances between L2 Mars Sun and Mars. I know that asking for an exact number would be stupid due to the elliptical orbit of Mars but I would like an estimated number in kilometers.

    $\begingroup$ Using my 3D diagram script here, space.stackexchange.com/a/57679/38535 I get L2 at 1.00476343 & L1 at 0.99525165. That's the distance from the Sun, in Martian astronomical units, so multiply those numbers by the mean distance from the Sun to Mars. Of course, the actual distances will vary a bit due to the eccentricity of Mars's orbit. Some people will say we shouldn't even be talking about Lagrange points of non-circular orbits... ;) $\endgroup$
